Powerbelts might not be the best choice for your Black Diamond. They were mediocre at best for accuracy out of mine and went veryeradicate at longer ranges out of my rifle.




I got much better results with Shockwaves. Something I forgot to ask was is this the 22" barrel model or the XR with the 26" barrel. If it is the shorter model, try starting your Triple Se7en loaded out even lower at say 85 grains, just to see what happens.



If you want to shoot a slip fit projectile, I would suggest a slip fit conical. I shoot the 460 grain No Excuse Conicals out of mine, and as you can see I only use a 85 grain of 3f or 80 grain of Triple Se7en load. I was told I could get even better accuracy if I stuck a wad between the powder and the conical. I admit I have not tried that option yet, but will in the future. This was shots off a set of shooting sticks and I never swabbed the barrel.

I am surprised the Black Diamond is being so hard to find a load for. Normally the rifle will shoot about anything you stuff down it. You might want to try lighter loads and if that does not work, then kick the charge up a couple times and see what happens...

Cheap Shots were also a very good shooting projectile out of the rifle. I was shooting them for fun mind you, but with the bullet design they would be more then able to take deer down for you.

Good luck with your rifle. There is nothing more frustrating when you can not get a rifle to shoot... Been there, done that, got the T-shirt.
